IMPROVEMENT iN SELF-ADJUSTING TELEGRAPHIC RELAYS.

Specification forming part of Letters Patent No. 82,639, dated September 29, 1868.

To all lwhom 'it may concern.-

Be it known that I, LEWIS H. REYNOLDS, ot` Goshen, in the county ot Orange and State of New York, have invented a Self-Adj usting Telegraphio Relay; and I do hereby declare that the following is a full, clear, and exact description ot' the construction and operation ot' the same, reference being' had to the annexed drawing, making a part of this specification, in whicha a is a double electro-magnet (composed of soft iron) or two electro-magnets, placed side by side in the helix b b, (composed of line covered copper wire,) the one electro-magnet being stationary, the other, its lower part working on a hinge or pivot at c c, and its upper part connected, by a string or rod, d, to armature-bar e ot' the common relaycommon relay being represented on right-hand side of red line-sulicient space being' allowed in helix I) b to allow one of the magnets a a alittle play. The helix b b is connected, by wires running' underneath, to helix ffot' common relay, thereby makingthe helices one continued wire. When an electric current is passing through the wire the positive poles ot` mag'- nets a a being together, they repel, while an mature g ot' common relay is attracted to its own magnet, so that the repulsion ot one nearly counteracts the attraction of the other, thereby making a seltadjusting; relay.

NVha-t I claim as my invention, and desire to secure by Letters Patent, is-

The double electro-magnet, or two electrolnagnets, placed in a helix or helices, with their like poles near cach other, and attachnient to armature or armature-imi' ot' common relay, so that their repulsion will counteract, or nearly counteract, the attraction ol' armaA ture ol common relay to its` own magnet.
